Abstract
The invention discloses heat-resistant porcelain clay for manufacturing a porcelain product and heat-resistant porcelain made from the same. The heat-resistant porcelain clay for manufacturing the porcelain product is characterized in that the sintered product contains the following components in percentage by weight: 50 to 70 percent of SiO2, 15 to 30 percent of Al2O3, 0.2 to 1.5 percent of Fe2O3, 0.1 to 1 percent of TiO2, 0.05 to 2 percent of CaO, 0.1 to 2 percent of MgO, 0.5 to 6 percent of K2O, 0.5 to 6 percent of Na2O, and 1 to 9 percent of Li2O. The heat-resistant porcelain made from the heat-resistant porcelain clay combines the advantages of the porcelain and the porcelain product; the water absorption of the product is within 5 percent; the product has compact texture and high porcelainization degree, is durable and easily cleaned and can be used for cooking food on an open fire furnace; and the thermal shock resistance of the product reaches no cracking during exchanging heat at one time under the environment of between 400 and 20 DEG C.
Description
Technical field
The present invention relates to ceramic field, specifically a kind of heat resisting porcelain mud that can be used for making the porcelain product and with its heat resisting porcelain of making.
Background technology
The heat resisting porcelain product (referring to that thermal shock resistance passes through 300～20 ℃ of temperature heat exchanges once, the ceramic product that product does not split) of successfully producing and having sold on the market in ceramic industry at present, its quality is all ceramic, the product water-intake rate is greater than 5%.Because ceramic product quality is more loose, add that water-intake rate is larger, daily ceramic product particularly, in heating repeatedly, contacting foodstuff and water logging are washed etc. under condition, have reduced work-ing life.And the daily product porcelain degree of porcelain is high, and porcelain is closely knit, and water-intake rate remains on (this characteristic is the technical requirements of GB/T 3532-2009 " domestic porcelain " standard) within 5%, and work-ing life is longer.Although conventional porcelain product has health, is easy to clean, long-lived advantage, but there is the relatively poor weakness of heat-resisting degree, by standard code, the heat-shock resistance of porcelain only needs once not split 180～20 ℃ of environment heat exchanges, this characteristic limitations porcelain product cooking food on the naked light stove and accessory.Due to porcelain and ceramic daily product existent defect separately, be difficult to satisfy the modern consumption crowd to the service requirements of daily heat resisting porcelain product.
Summary of the invention
For overcoming above-mentioned deficiency, the invention provides a kind of heat resisting porcelain mud that can be used for making the porcelain product and with its heat resisting porcelain of making.
The heat resisting porcelain mud that can be used for making the porcelain product of the present invention is characterized in that the product after burning till contains following composition: SiO by weight percentage
250～70%, Al
2O
315～30%, Fe
2O
30.2～1.5%, TiO
20.1～1%, CaO 0.05～2%, MgO 0.1～2%, K
2O 0.5～6%, Na
2O 0.5～6%, Li
2O 1～9%.
Above-mentioned heat resisting porcelain mud is preferably made by following compositions in weight percentage: lithium feldspar 1～5%, triphane 50～70%, quartz 2～5%, kaolin 10～20%, clay 6～14%, talcum 1～5%, heat resisting porcelain waste product material 8～15%.
Wherein, the lithium feldspar can reduce the fusing point of porcelain mud, thereby reduces the product firing temperature; Triphane can reduce thermal expansivity, and the heat-shock resistance of product is improved; Quartz can play product base substrate skeleton function; Kaolin can improve the plasticity-of product blank forming process; Clay can strengthen pug in the mobility of casting process, improves simultaneously the physical strength of molding blank; Recycle the scrap of heat resisting porcelain production process, these scrap were calcined, when reusing, can reduce product firing temperature and time, reduce product in decomposition and the volatilization of sintering process mineral composition, reduce the product size error, improve the heat-shock resistance of product, realize simultaneously resource reutilization, save production cost, prevent from that waste from externally losing to put and contaminate environment.
Heat resisting porcelain of the present invention is characterized in that, is made by above-mentioned heat resisting porcelain mud.
The production method of heat resisting porcelain of the present invention is characterized in that, be with above-mentioned heat resisting porcelain mud through batching, ball milling, sieve, dewater, press mud, old, mud refining, slip casting, biscuiting, glazing and burn till after, make product.
Best glazing mode in described production method is different from traditional glazing mode, it is manual combination of soaking glazing and glaze spraying, after specifically first product being soaked for 2～5 seconds in concentration is the glaze liquid of 28～32 degree Beaume, then to adopt spray gun to add spray concentration be the glaze liquid of 55～65 degree Beaume.The glazing mode of this mixing can make glaze layer absorption evenly, avoids conventional in uneven thickness that glaze sagging that glazing causes and the direct glaze spraying of conventional base substrate cause that soak, and product glaze layer glaze plane defect after burning till reduced.
Described temperature of burning till is preferably 1260～1300 ℃.
The heat resisting porcelain set that heat resisting porcelain mud of the present invention is made the advantage of ceramic and porcelain product, the product water-intake rate is in 5%, quality is closely knit, the porcelain degree is high, durable in use, be easy to clean, and can be on direct-fired heater cooking food, its heat-shock resistance reaches under 400～20 ℃ of environment heat exchange and does not once split.
Embodiment
The present invention will be described in detail to reach by the following examples Comparative Examples.
Embodiment: get by weight percentage lithium feldspar 2%, triphane 60%, quartz 3%, kaolin 15%, clay 7%, talcum 3% and heat resisting porcelain waste product material 10%, through batching, ball milling, sieve, dewater, press mud, old, mud refining, slip casting, biscuiting, glazing and burn till after, make product; Wherein, glazing be first with product after concentration is to soak for 5 seconds in the glaze liquid of 30 degree Beaume, then to adopt spray gun to add spray concentration be the glaze liquid of 60 degree Beaume; Described temperature of burning till is 1280 ℃.
After testing, the product after burning till contains following composition: SiO by weight percentage
